LOCK.

Specification of Letters Patent.

Patented d1 une 22, 1915..

To all whom it may concern Be it known that I, SELBY G. CARR, a citizenof the United States, residing at Muskogee, in the county of Muskogeeand State of Oklahoma, have invented certain new and useful Improvementsin Locks, of which the following is a specification.

This invention relates to looks and has as one of its objects to providea look so constructed that itvwill be unnecessary to use a key in orderto adjust the lock to secure the door to which it is applied.

Another object of the invention is to provide a lock which may be soadjusted that it can not be unlocked from without even by the use of aduplicate key.

' The invention has a further object the provision of a lock possessingthe characteristics above mentioned, Which lock may,

without disarranging any of its elements, be

readily and quickly applied'to a door of any thickness within reasonablelimits, the adjustment of the lock to a door of gi thickness beingaccomplished prior to the fitting of the lock to the door and withoutthe necessity of repeated trial fittings and adjustments.

The invention also aims to provide a look so constructed that it may bereadily adjusted so that it may be unlocked from with- A in or without,without the use of a key;

so that it may be unlocked from within without the use of a key, andfrom without by the use of a key; and, so that it may be unlocked fromwithin but-cannot be unlocked from without even by the use of duplicatekeys.

Another feature of the invention resides in a novel tumbler mechanismarranged for actuation by'the use of a proper key and, upon actuation,to adjust the lock mechanism so that rotation of the outer knob willserve to unlock the door.

Still further the invention aims to provide, in a look, a novel form ofescutcheonplate so constructed that the door to which the lock isapplied will expand and contract without the plate becoming loosened andwithout the lock mechanism being in any way affected.

Still further the invention contemplates the provision of a lock havingall of the characteristics above mentioned, which look may without anyconsiderable adjustment of parts he applied and attached to a dooropening inwardly or outwardly.

For a full understanding of the inven- I tion reference is to be had tothe following description and accompanying drawing, in

which Figure 1 is a vertical longitudinal sectional view through thelock, the parts there of being adjusted to permit of the door beingopened from within or without by the verse sectional View on the line4-4 of Fig.

Fig. 17 is a vertical transversesectional view on the line 1717 of Fig. 1 looking in the directionindicated by the arrows.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

In the drawings the inside escutcheon plate. is indicated by the numeral1 and the outside escutcheon plate by the numeral 2.

By referring to Figs. 1, 2 and 3 of the drawings it will be observedthat each of the I plates is relatively thin and that each is providedat its periphery with a relatively narrow flange 3, the edges of theseflanges resting against the faces of the door against which the platesare secured. As before stated, the lock embodying the present in ventionis adapted for application to doors of various thicknesses and to thisend means are provided for adjustably connecting the two escutcheonplates. The plate 2 is formed upon its inner-side or face with two ormore interiorly threaded sleeves 4, and screws 5 are fitted throughopenings in the plate 1 and are adjustably threaded into the saidsleeves, the door which is indicated in the drawings by the referencecharacter D being formed with openings 6 receiving the said sleeves 4and screws 5. At this point it is to be noted that inasmuch as the edgesof the flanges 3 bear against the opposite faces of the door D, the doormay swell or contract without the plates becoming loosened. Furthermore,it will be noted that inasmuch as the sleeves 4 are formed upon theinner face of the escutcheon plate 2, the plate iswithout visible meansof attachment to the door and'consequently, cannot be readily removed byone endeavoring to disturb the lock-mechanism.

The door D is formed with a mortise 7 and with an opening 8- whichextends therethrough andis in communication with'the mortise. Th eescutcheon-plates 1 and 2 are formed respectively, with openings 9 and10 which register with the opening 8 when the escutcheon plates arevproperly positioned upon the door. The outer faces of the escutcheonplates 1 and 2 are formed respectively with flanges 11 and 12 whichsurround the openings 9 and 10, although of greater diameter than therespective openings.

The inner and outer knobs ofthe door are indicated in general by thenumerals 13 and .14, and the outer knob 14 consists of a section 15 anda cap-section'lfl which has its peripheral ortion overturned about theedge of the flare portion of the section 15 as indicated at 17. The saidsection 15 is reduced in diameter, as at 18, and is further reduced indiameter, as indicated at 19, and is formed upon its last mentionedreduced portion with a circumscribing rib 20. In reducing the section asat 19, a shoulder is formed which is spaced from the rib and thematerialof the escutcheon plate 2 between the opening 10 and flange 12is received between the said shoulder and the rib 20. The flange 12projects into the reduced portion 19 of the knob section. At this pointit willbe seen that the knob is connected for turning movementwith theescutcheon plate 2, but that it cannot be disconnected from the plateexcept by destroying either the plate or the knob.

The knob is provided with a tubular shank '21 which is formed with aslot 22 and this shank is open at both ends, its inner end 20 upon theshank of the knob section 15 and the material of the escutcheon platewhich lies between the opening 9 and flange 11 is received between theshoulder formed by reducing the shank 25 as at 27, and the rib 29,

the flange 14 projecting into the reduced portion 28. At this point itwill be observed that the shank of the outer knob slidably fits withinthe shank of the, inner knob but that due to the engagement of the rib26 in the slot 22 these knobs are at all times held for turning movementin unison; however, the escutcheon-plates 1 and 2 may be adjusted towardor from each other without disturbing this connection.

The casing for the bolt of the lock is indicated in general by thereference numeral 30 and .is carried by an attaching plate 31 formedwith the. usual opening 32 for the passage of the head of the bolt. Asshown in Figs. 1, 2 and 3 of the drawings, the casing 30 is formed inopposite side walls with openings 33 in which are mounted the ends of arocker 34 which consists of a hub provided with oppositely extendingshoulders 35 arranged to coiiperate with lugs 36 at the ends of the armsof a yoke 37 located at one end of the latch-bolt. The lock and latchbolt is indicated in the drawings by the numeral 38 and the head thereofis indicated at 39 and has a rounded nose 39" as distinguished from thenose of the ordinary latch-bolt head, which is flat. The shank of thebolt 38 is formed with a slot 40 in one end of which is normally engagedthe usual tubular post 41 which is integral with one side-wall of thecasing which receives the usual screw 42 which serves to hold theopposite side-wall of the casing in place. A spring 43 is arrangedwithin the slot in the shank of the bolt and bears at' one end againstthe post 41 and at itsthat upon rotation of the rocker 34 in one Ydirection or the othcr, the bolt will be retracted owing to theengagement of the shoulders 35 against the lugs 36, against the tensionof the spring 43 so as tomove its head into the casing and outof lockedposition. For a purpose to be presently explained, therocker is formed.in each end with a plurality-of diametrically oppositely locatednotches 44 and the notches at one end of the rocker alternate with thenotches at the other end, or more specifically speakdrawings that thetubular shank 21 of the outer knob fits rotatably within the saidrocker.

The spindle of the lock is formed in three sections, one of which isindicated in general by the reference numeral 45, another by the numeral46, and the third by the numeral 47. The spindle section 45 consists ofa stem which is rectangular in crosssection and which is provided at oneend with a pyramidal head 48. The head 48 is received within acorrespondingly formed opening 49 and a disk 50 which is secured totheinner end of the barrel 52 of a keyoperated tumbler mechanism which isdesigned for actuation to rotate the spindle section For a purpose to bepresently explained this disk 51 is provided upon its periphery with aradially projecting lug 52. The barrel is rotatably carried within acasing 53 which has one end fitted as at 53 in an opening formed in thesection 16 of the outer knob, the said section having a flange 53 whichis overturned about a circumscribing rib 53 formed upon the casing 53.The casing 53 is formed with a number of openings 54 which extend in aseries longitudinally of the casing, and at points diametricallyopposite the ,openings 54 with openings The barrel 52 has a key-slot 66extending therethrough and intersected by a. number of recesses 57 inwhich are fitted the tumbler pins in a manner which will now bedescribed. Each of the recesse's 57 is widened as at 58, whereby toafford, a shoulder 59 located near one end thereof. Each ,of the tumblerpins is indicated by the numeral 60 and each has a laterally porjectinglug 61 against which bears one end of a spring 62 which is housed Withinthe widened portion of the recess in which the respectivetumbler pin isseated, the other end of the spring bearingagainst the shoulder 59, asclearlyshown inFig. 13 ofthe drawings. That side of each tumbler pin 60opposite the s'idefrom which the ,lug 61 projects is recessed as" at '60to form laterally-projecting heads 60 and 60 located respectively at theupper and lower ends of the pin, the head 60 being beveled upon itsunder side as indicated at 60 the head 60 extending a greater distanceoutwardly than the circumferential radius of the under surface of thelug 61, this head projecting a greater or lesser distance into therecesses 54 of the casing 53.

By referring to Figs. 13 and 14 it will be observed that the heads 60 ofthe latchpins 60 have their upper ends normally located a greater orless distance inwardly of the circumferential surface of the barrel 52and that the springs 58 normally hold the pins with the heads 60projecting into the openings 54 in the casing 53, the barrel 52 being inthis manner held against rotation in the said casing, although it willbe seen that upon the insertion of a proper key into the slot 56 thebeveled under sides 60 of the heads60 will be engaged by the key and thepins will be moved upwardly to such an extent as to bring the lower endsor heads 60 flush with the circumferential surface of the barrel 52 andthe barrel may then be rotated in the casing 53. A'shell 63 is fittedupon the casing 53 and serves to exclude dust from the tumbler mechanismabove described, and at its inner ends this shell is extended to form aflange 63 the ends of which form shoulders .63 against which the lug 52upon the disk 50 is designed to engage when the barrel 52 is turned inone direction or the other, the rotative movement' of the barrel beinglimited by reason of such engagement.

The section 46 of the spindle is in the nature of a sleeve which isformed throughout its length with a bore 64 which is of a contour tosnugly receive the squared stem of' the section 45, in the mannerclearly shown in Figs. 1, 2, 3 and 10. The section 47 of the spindle issubstantially rectangular in cross-section throughout the greaterportion of its length, as clearly shown in Fig. 9 of the drawings, andthroughout its said portion is threaded at its .corners, as at 65.Throughout the remainder of its length the said section 47 is reduced indiameter, as at 66 and is circular in cross-section. Loosely fitted uponthe spindle section 45 is a sleeve 67, the bore of. thissleeve beingcircular and indicated at 68 and of a diameter to receive the saidspindle section 45 for turning movement. The sleeve 67 is provided witha laterally projecting lug70-which is designed to engage in one oranother of the notches 44 in the rocker 34. By referring to Figs. 1 and2 of the drawings it will be noted that .the lug 70 projects through theslot 22 in the knob-shank 21 and that one end of the spindle section. 46bears I against the said sleeve. A spring 71 is fitted upon the spindlesection 45 and bears at one end against the disk 50 and at lts other endagainst the said sleeve 67 so as to hold the sleeve in position againstthe spindle section 46. This spring serves also to normally hold thesleeve 67 in position with its lug 70 engaging in one or another thatthe lug 70 projects through the slot 22 and engages in the notches 44,and due to the engagement of the rib 26 in the slot 22, rotation ofeither knob in either direction, when the lug 70 is engaged in any ofthe notches 44 will serve to retract the lock-bolt. It will be apparent,however, that when the lug is not in engagement in any of the notches 44either knob may be rotated in either direction without in any wayaffecting the latch-bolt.

For a pur ose to be presently explained a sleeve-nut 2 is threaded onthe squared portion of the spindle section 47 and this sleeve nut'constitutes an adjustable abutment for that end of the spindle section46 opposite the end which is engaged by the sleeve 67.

Thereduced end 66 of the spindle section 47 fits within the stem 76 of apush-button 77.

This button 77 is mounted for sliding movement in a cylindricalstamped-in portion 78 of the cap-section 24-of the inner knob and isnormally held in the position shown in Fig. 1 25- of the drawings bymeans of a spring 79 which bears at one end against the back of thebutton and at its other end against lugs 80. which are stamped-in atdiametrically opposite points from the inner end of the portion 78. Thecap-section 24 of the knob at the outer end of its portion 78 is stampedor otherwise formed with a rib 81 against which abuts the peripheralportion of the button 7 7 By s0 mounting the button, pressure insertedagainst it in the manner illustrated in Fig. 2 of the drawings willresult in the section 47 being slid to the right in Fig. 1 of thedrawings, correspondingly moving the section 46 and the sleeve 67whereby to move the lug 70 out of engagement in the notches 44 in therocker 34.

It will be apparent that due to the provision ofthe sleeve-nut 72 theseveral sec- 45 tions of the spindle may be adjusted with respect toeach other so as to permit of the lock being mounted upon a door of anythiclmess within reasonable limits and for a purpose which will bepresently'pointed out 5.0 a collar 82 is arranged upon the squaredportion of the spindle section 47 at that end thereof adjacent thereduced portion 66 'of i the saidspindle section, and a pin 83 is fittedthrough the said collar 82 and the said spindle section whereby to holdthe collar in place. The collar is formed upon its under side with a lug84 having a beveled under face 85, the forward end of this lugconstituting a shoulder or abutment for engagement with a member of adetent device which will now be, described.

In connection with the spindle consisting of the several sections abovedescribed, the invention contemplates the provision of a detent devicefor holding the spindle section 47 in such' position that the lug willbe disengaged from the notches 44 and this device will now bespecifically described. The detent mentioned above is in the nature of aplate 83 having its lower end bent back upon itself at an angle as at 84and bifurcated as at 85. A rivet 86, or the like, is secured upon theinterior surface of the section 23 of the inner knob and fits within thebifurcation 85 in the manner illustrated in Figs. 1 and 2 of thedrawings.

The plate 83 is formed with an opening 86, the lower portion of which issubstantially circular and the upper portion is of segmental outline, asindicated at 87. A portion of the shell-section 23 is struck-in as at 88and fitted between this portion and the corresponding portion 24 are theends 89 of a leaf-spring 90, the end-portions of the spring being bentback at an angle toward each other as, at 91 and secured in suchposition that the body portion of the spring will extend along a linewhich is a chord of the circle described between the portion 25 of thesection 24. At a point midway between its ends the body portion of thespring is struck-up so as to form an upstanding lug 92. At its upper endthe plate 83 is formed with a forwardly projecting tooth 93 which restsupon the upper surface of the body portion of the spring 90 and isdesigned to engage the said surface at one side or the other of the lug92. .The plate, beside the tooth 93 is bent to extend rearwardly atright angles to the plane of the body portion of the plate, as at 94,and thence to extend upwardly as at 95, this latter portion fittingwithin a finger-piece 96 having an arcuate base 97 which serves to closea slot 98 in which the finger-piece works, this slot being formed in theupper side of the section 23 of 'theinner knob in the manner illustratedin Fig. 1 of the drawings.

By referring to Figs. 4, 5 and 7, it will be observed that the lower orcircular portion of the opening'86 is arranged to conform to thecross-sectional contour of the collar 82 and that when the wedge-shapedlug 84 is uppermost this collar may pass through the opening, the lugpassing through the upper or segmental portion of the opening. However,it will be observed by referring to Fig. 4 of the drawings that when thecollar- 82 is rotated to position with its lug facing downwardly, whenthe detent is in normal position, the forward end of the lug will restagainst the rear face of the plate 83*. It will further be observed frominspection of Fig: 5 that should the plate 83 be swung to the right toassume the position illustrated in the said figure, the end of thecollar 82 will abut against the rear face of the deagainst movement toassume the position shown in Fig. 2.

In order that the inclined face of the lug 84 may readily pass over thewall of the opening 86, the face ofthe plate is formed with an arcuaterib- 98' which is convex in cross section and which extends along thelower side of the said opening.

The lock-strike employed in connection with the locl:,-aboye described,consists of a plate 99 which is formed near its upper and lower endswithslots lOO and this plate is formed between the slots 100 with arelatively wide-slot 101=and at one side of this slot is thickened asat102 and-extended to form a tongue 103 which is curved laterally so as topermit of the ready movement of the loclebolt into engagement with thestrike. A plate 104, is disposed against the .plate 99 andin one side isrecessed asat 105, the upper andlower walls of the recess being beveledas at 106 and slidably receiving between them the'thickened portion 102of the plate 99. Screws 107 are fitted through openings 108 formed. inthe .plate 104 and project through the slets 100 and are threaded intothe door trame in the usual -manner. It will be observed that the plate104 is formed at one edge'with a laterally projecting flange 109 whichcloses the space between the-face of the. plate and the edgeface of thedoor and this flange prevents the insertion of a knife, or the like,between the door and'the strike for the purpose of shifting thelock-bolt to released position.

l[t ,will be readily understood that by ad;

justing the plate 104: upon the plate 99, the position of that wall ofthe opening of the strike, against. which the lock-bolt engages, may bevaried sowthata snug engagement may be secured between these elements.

L It will be understood by referring to Fig. 1 of the drawings that.with the parts in the position shown. in this figure a rotation ofeither knob in one direction or the otherwillresult. in the lock-boltbeing retracted-from locking engagement :with the lock-strike andconsequently the door may be opened from .within or from Without whenthe parts are so relatively-positioned. Should it be desired to'lock thedoor so that it could only be openeditr'om .without by the use of aproper key, the button 77 is;-,pressed inwardly as indicated in Fig. 2of the drawing and against the tension of the spring 79.

- This movement of: the button will result in a cor-responding -motement of the collar-82 and as the wedge-shaped lug 84 upon this collarrides over the lower side of the wall of the opening Bfiflthedetent-plate 83 will be moved downwardly against the tension of thespring'90 and the abrupt end of the said lug '84 will engage behind thedetentplate in the manner shown in Fig. 2 of the drawings. As soon asthe button 77 is relieved of pressure, it will be automatically returnedto the position shown in Fig. 2 of the drawings through the medium ofthe spring 79. The movement of the collar 82 and the section -17 of thelock spindle, above described, will result in a corresponding movementof the section 4-6 together with the sleeve 67 so that the lug 7 0 willbe moved out of engagement in the notches in the rocker of the lock.With the parts thus po-. sitioned, either knob may be turned in eitherdirection without ,in any way affecting the lock-bolt. It will beunderstood from inspection of the drawings that the three sections ofthe spindle are connected for rotation in unison so that should eitherof the sections be rotated, the others would be similarly moved.Consequently, should the proper key be inserted into the barrel 52 andshould the key be turned so as to rotate the barrel, a similar movementwill be imparted to the section L? of the spindle and if this 'lnovementis continued until the abrupt end of the wedge-shaped lug 84iregisterswith the portion 87 of the opening in the detent 83*, the spring 71 willact immediately to shift the section 4;? in the direction. of the innerknob and to approximately the position shown in Fig. 1 of the drawings.This movement of the spindle sections will result in an engagement ofthe lug in one.or another of the notches in the rocker of the lock, androtation of the outer knob will then result in the retraction of thelock-bolt.

, It will be understood that with the parts arranged as abovestated, thedetent plate will maintain the positionshown in Fig. 4

.of the drawings.

ment of :the collar 82 until the lug 84 has passed over the lower sideof the wall of the 7 opening in the detent-plate 83" and this plate hasbeen returned to normal position, or in other words, the position shownin Fig. 2 of the drawings, in which position the abrupt forward faceofthe lug will rest against the respective side of the said detent-plate.The finger-piece is then-swung to the right so as to move thedetent-plate to approximately the position-shown in Fig. 5, in whichposition the end of the collar 82 will rest in engagement with the rearside of the plate at all positions in the rotative movement of the saidsection of the spindle so that even should a proper or duplicate key beinserted into the barrel-52,,and should the barrel be rotated, thespindle section 47 would at no pointin-its rotativeimovement assume aposition which would permit it to be moved through the opening 86"in thedetent-plate through the action of the spring 71. To restore the lock toits normal condition, however, it is only necessary to slide thefingerpiece 96 to the left from its position shown in Fig. 5 so that itwill assume the position shown in- Fig. 4, after which downward pressureon the finger-piece as in Fig. 6 will release the spindle sections 46and 47 for forward sliding movement to seat 7 O in the notches in therocker.

From the foregoing description of the invention it will be seen thatthere is provided a lock, the parts of which may be readily the lug andquickly adjusted. so as to permit of the nesses and that the screws 5 ofthe extension bolts are to be threaded onto the sleeves 4 a greater orless distance depending upon the thickness of the door. In adapting thelock for application to doors of different thicknesses, it will ofcourse be necessary to adjust the sleeve-nut or collar 72 upon thespindle section 46, but'aside from this no other adjustment of the lockmechanism is required. I In adjusting the lock for application to a doorof a given thickness, the sleeve nut 72 is threaded along the spindlesection 47 for a distance equalto a part of the thickness'of the door,after which, the lock can be applied without further adjustment... Ifdesired, a fixed point may be marked upon the said spindle section and ascale designed indicating inches and fractions of inches, and inaccordance with which scale, and predetermined point 72the sleeve-nutmay be adjusted after a measurement of the door to determine itsexactthickness. 5 Having thus described the invention what is claimed asnew.'is:-
